You have some valid points, bar the last one. Many religious do not reject to the use of weapons in general. Most proponents of the NRA are of what religious stance? You guessed Christians. Many world leaders are pro-war and have NO problem ordering their national defence to use weapons of mass destruction.

So religion doesn't really reject that at all, as a matter of fact I could find plenty of biblical quotes supporting mass destruction and obliteration.

Such as:

Judges 5:31

"So may all your enemies perish, O LORD! But may they who love you be like the sun when it rises in its strength."

And, Science is not a united collective of people with one central symbol of leadership. A religion is. You don't have to convince all scientists, only the ones who are straying. In order to get a religion to admit that it's wrong, you have to convince nearly all of them. At least the most pious of them.

Science argued that some races were less intelligent by virtue of various physical traits. Religion dissented.

Racism is not science.

Religion has been used to justify racism for centuries, notably in the US with Mormons and Southern Baptists, the latter of whom founded a new Church in defense of slavery using Biblical justifications and the claim that the Curse and Mark of Cain was black skin.

Science experimented on human subjects who were poor, or of a particular racial group, without their consent. Religion objected.

Subjugation of the weak is not science.

Religious used devices like the wheel, the rack, the stake, the pillory, the iron maiden, and the scavenger's daughter for centuries to torture or terrorize human subjects of particular groups (heretics, witches, scientists and other undesirables) without their consent.

Science may create WMDs, but don't tell me religious object to using them.

Religious Southern Baptist Harry Truman dropped two atomic bombs on civilian populations in Japan; arguably unnecessary, the worst use of WMDs in history, and the start of the global arms race.

Religious Nazis systematically exterminated millions of Jews during the Holocaust using industrial technology and methods, an undertaking made possible by long-standing Christian antisemitism. The atomic bomb was invented because of them.

Religious crashed loaded passenger planes into skyscrapers in New York City, making creations of science into WMDs.
